SAS/FSP Software Procedures Guide |
If you are an applications developer, you can use the FSVIEW procedure as the basis for data entry applications and editing applications. The FSVIEW procedure enables you to customize the application environment to suit the needs of your users. Customization can include
The feature of the FSVIEW procedure that makes this customization possible is the FORMULA entry. Formula entries are SAS catalog entries of type FORMULA that are created by the FSVIEW procedure to record the following information about the FSVIEW session:
Note: Formats and informats that are specified in the data set
or by using FORMAT and INFORMAT statements in conjunction with the PROC FSVIEW
statement at procedure invocation are not recorded in the FORMULA entry.
The format and informat for computed variables are always stored in the FORMULA entry. If a FORMAT or INFORMAT command for a computed variable does not specify a valid format or informat, it is ignored.
If you specify
a catalog name or a complete formula name when you open an FSVIEW window (by
using the FORMULA= option in the PROC FSVIEW statement, the formula-name argument in the FSVIEW command, or the FORMULA=
option in the BROWSE, EDIT, and NEW commands in the FSVIEW window), a FORMULA
entry is created automatically when the FSVIEW window is closed. You can also
create a FORMULA entry by issuing a SAVE FORMULA command in the FSVIEW window.
If you specify only a catalog name, the FSVIEW procedure uses the name of
the displayed data set as the formula name.
To load an existing FORMULA entry when you invoke the FSVIEW procedure, use the FORMULA= option in the PROC FSVIEW statement or the formula-name argument in the FSVIEW command. You can also use the FORMULA= option in the BROWSE, EDIT, and NEW commands in the FSVIEW window to load a FORMULA entry for additional FSVIEW windows that are opened during the FSVIEW session. You can use the FORMULA command in an open FSVIEW window to change the FORMULA entry that is used for the window or to load a FORMULA entry if none was used when the window was originally opened. (The FORMULA command is valid even if you do not specify a formula catalog when you invoke the FSVIEW procedure.)
